Add section on mailinglists/newsletter

I’d like to see a section on privacy friendly mailinglists or newsletters. One can self-host mailman, but I was looking for a mailinglist that I can just use and trust. There is a decent feature overlap of mailinglists and newsletter systems. It would be great to have something that does not store any emails.

Mailing list/newsletter are like an even slower version of the Fediverse, where a mailing list group is like an instance of Mastadon… or a forum like this, even?

With the difference of the interface, which matters to people a great deal.
Your argument would also include messengers for example.

I am not aware of a forum software or fediverse instance that does not store any data and only transmits emails?

I assume this is where something like Substack would live?
